Great idea and suggestion. Most regular businesses must compete....you know, good service, qualiity product, good value for the buck and prompt service.
There are however many businesses that must schedule their services differently, like plumbers, service companys etc. ( 8:AM to noon)
It will be difficult to get the doctors to improve much because they can only see so many folks during a day and some of the visits take longer than the average alloted time.
Here in Lake Havasu City, AZ, the majority of the patients are old farts like me and require a lot of doctoring, so waiting is just a good time to read my copy of Kit Kar mag.
Most of the time my appopintments are pretty close on schedule but occasionally they get pushed back.
I'm not disaggreeing with you, some quality and performance guidelines are needed to force the doctors to upgrade their service.
